I'm by no means a Linux PC hacker, so I thought I was playing it safe by ordering an Intel board from my local computer shop. I knew that the DG965WH could be coaxed into working, so I asked for the DG965OT, which is the micro-ATX version that would fit in my Antec NSK2400 case.

Instead of getting the DG965OT I requested, the shop ordered the DQ965GF, which is part of Intel's Executive line of business-oriented boards. I didn't think the board could differ all that much from the DG965OT that I wanted, but the persistent problems I am encountering are leading me to believe there may be important distances between them.

The first problem is the utter lack of audio for roughly 95% of my attempts to use the system. I've reinstalled countless times, picking boot options like intelfix and dragon2 to account for known Intel issues.

The forums mention alsaconf and alsamixer as a way to get the sound back, but it's not that easy for me, since aumix, alsamixer and other alsa tools simply hang. Even a kill -9 cannot get rid of those processes once they've hung. I've even updated the alsa driver to alsa-driver-1.0.14rc4 and the problem remains. I still cannot get alsamixer to work at all.

The other problem is a constant tic or pause in the video playback, which occurs at least once every few seconds, regardless of whether or not I have audio. The signal quality is otherwise good, which tells me that the frequent catch I see and hear is not due to signal problems.

I sincerely hope that a DG965OT board does a better job, since I am about to ask my computer shop to get that board in for me to try.

I updated the BIOS on the DQ965GF and didn't notice any real improvement.
Given the way alsamixer always hangs, I am increasingly suspicious of the pair of HD-5500 cards I installed after the computer shop assembled and tested the base PC. I tried running Ubuntu Feisty with the HD-5500 cards installed, and it was similarly unstable at audio-related tasks.

It would seem that my problems would probably vanish if I pulled out the HD-5500 cards, but that wouldn't be a very attractive long-term solution.

I am inclined to disagree with you on this count. From my quick searching yesterday there are a number of users experiencing audio problems with that type of mainboard. As you said it is not a long term solution, but taking the HD cards out and trying it would negate an issue between them and the mainboard. My suspicion is that it won't make a difference.

I did a little more digging and would like you to try this if you have the time and inclination.
At a command line and as root:

Code:

modprobe snd-hda-intel

This should insert the required module into the modules list. Next we need to set up the configuration file.

We need to create a file

Code:

pico /etc/modutils/alsa

and then insert this into the new file.

Code:

# ALSA portionalias char-major-116 sndalias snd-card-0 snd-hda-intel

Then we need to edit the /etc/modules file

Code:

pico /etc/modules

and insert the following:

Code:

# ALSA portionalias snd-card-0 snd-hda-intel

Then we have to make sure everything takes:

Code:

update-modules

Try a reboot and see how you go with alsamixer then, failing that you may want to create the file .asoundrc in the mythtv users home directory. As mythtv user:

Code:

pico ~/.asoundrc

Into this new file paste the following:

Code:

pcm.hda-intel { type hw card 0 }

ctl.hda-intel { type hw card 0 }

This is a very basic .asoundrc file and will hopefully get your card working.

I appreciate the detailed responses, especially from Girkers. I tried those commands, but they offered no improvement while the HD-5500 cards were on the main board.

The big improvement came when I removed both HD-5500 cards and attempted a reinstall using the dragon2 option. Immediately after the post-install reboot, before the second half of the setup, I followed the instructions from another post and blacklisted cx88-alsa. Since the HD-5500s were not there to fight with ALSA, I was finally able to set alsamixer and save the settings. After that I shut down and reinstalled the HD-5500s. From that point, I was reliably getting sound and could continue to work out other issues. The sound quality is still a bit choppy, with little clicks or stutters occurring every few seconds, but it is a lot better than no sound at all.

I just swapped the DQ965GF board out so I could replace it with the DG965OT board, which closely resembles the DG965WH board (Dragon 2.0). The only discernible difference between the DG965WH and my new DG965OT appeared to be the form factor and number of PCI slots.

I still had to blacklist the cx88-alsa module prior to inserting the HD-5500 cards, but once I did, there was none of the stuttering or choppy playback that I had consistently encountered on the old DQ965GF. My impression from all this is that the DQ965GF may be a good business PC, but it is not up for the task of running multiple HD capture cards. Having returned the DQ965GF board already, I won't have much to write about it here anymore.
